As we all know, Smoking or any open flames are not allowed in the gas station area.
The risk of a flammable atmosphere occurring is always present where fuel is handled.
Any possible ignition sources must be eliminated. it includes discharges from static electricity on objects or persons.
Here we are discussing static electricity generated by fluid flow.
Static electricity is generated when a low conductivity fuel flows in a non-conductive pipe.
The fuel will be positively-charged and the pipe wall negatively-charged.
Since the charges of the pipe wall cannot go anywhere, static electricity will accumulate as long as fuel flow continues.
The static charges in the pipe create an electrostatic field and conductive objects in the field will get an induced charge.
The induced charges can discharge either between two unbonded conductors in the system or to a tool or a person in the proximity.
Therefore, it is very necessary to use static conductive pipes to eliminate static electricity risks.
